However, PMC materials cured by thermal process require high temperature and are time-consuming. The electron beam (EB) curing technology allows its use at room temperature and reduced curing times, and this is one of the main advantages over thermal technology. The aim of this work is to investigate electron beam curable epoxy formulations to use in filament winding processes to produce composite material with similar or better properties than thermal curable composites. The study has been made with commercial epoxy resins and cationic initiators. The epoxy resin samples were irradiated for few minutes with total dose of 150 kGy. The glass transition temperatures (Tg) were determined by dynamic mechanical analyzer (DMA) and the result was 137 °C. The thermal process was carried out in a furnace following three steps: 4 h at 90 °C, increasing temperature from 90 °C to 130 °C during 4 h and 12 h at 130 °C. The total process time was 20 h. The Tg of this sample was 102 °C.135-138openAccesscomposite materialscorrosion resistancedensityelectron beamsepoxideshydrogen 4metalsradiation curingresinstemperature range 0273-0400 ktemperature range 0400-1000 ktensile propertiestransition temperatureArtigo de periódico1265Section B10.1016/j.nimb.2007.08.039https://orcid.org/0000-0002-7968-2117https://orcid.org/0000-0001-9035-8791
